一种基于索引结构的多语言界面实现方法

One Method for Multilingual Interface Implement Based on Index Structure

针对嵌入式系统软件设计中多语言版本实现程序空间利用率不高、通用性差的问题,本文介绍一种在C51环境下,通过为不同语言的字符建立多重索引,设计了基础字符库和显示界面字符串索引结构,在应用程序中通过指针简单调用实现在点阵式LCD液晶上的多语言显示,并且可通过单键实现语种切换功能,节约空间、简单实用。该方法已在设计的温室环境信息采集控制系统的运用中取得了很好的效果。

To solve the problem of the muhilingual version in embedded system software design, such as low utilization rate and low generality, a method is proposed which concludes multi-index constructing for different languages, basic character library and display interface designing and implementing the function of display on LCD using simple pointer calling in application program, also language shift can be done using single key, the design is based on C51 compile environment, thus the method has the characteristic of space saving and simple practical. The method using in greenhouse environmental information acquisition and controlling system is running properly in practice.
